In Laravel, services are an important aspect of the application architecture that helps organize and structure code. Services allow you to take business logic out of controllers and models, making the code more supported and reused.

Services in Laravel are classes that execute specific business logic of an application. These classes do not relate to a specific model or controller, they are self-contained and can be called anywhere in the application. This makes them ideal for rendering complex logic that should not clog controllers or models.

Organization of business logic:

Services allow you to remove complex logic from controllers, which makes the code cleaner and more structured. For example, if you have complex logic for processing orders, you can create an OrderService that is structured. For example, if you have complex logic for processing orders, you can create an OrderService that will contain all the necessary code to work with orders.

Reusing the code:

One of the main advantages of using services is the ability to reuse code. If certain logic is needed in several places of the application, you can create a service and use it wherever necessary.

$orderService = new OrderService();
$orderService->processOrder($orderData);

Dependency Injection:

Laravel supports dependency injection, which makes it easy to use services in controllers and other places. You can simply add a service to the class constructor, and Laravel will automatically implement it.

class OrderController extends Controller {
    protected $orderService;

    public function __construct(OrderService $orderService) {
        $this->orderService = $orderService;
    }

    public function store(Request $request) {
        $this->orderService->processOrder($request->all());
        return redirect()->route('orders.index');
    }
}

Creation and registration of services:

You can create services manually and register them in the Laravel service container via Service Providers. This allows you to manage the creation of objects and their dependencies.

public function register() {
    $this->app->singleton(OrderService::class, function ($app) {
        return new OrderService();
    });
}

Laravel Services is a powerful tool that allows you to organize the business logic of an application into stand—alone, easily manageable components. Using services makes the code cleaner, more structured, and easier to maintain. If you have complex logic that repeats in different parts of the application, bring it to the service — this will help you keep the code in order and avoid duplication.
